1303 Crete Earthquake
The 1303 Crete earthquake occurred at about dawn on 8 August. It had an estimated magnitude of about 8, a maximum intensity of IX (''Violent'') on the Mercalli intensity scale, and triggered a major tsunami that caused severe damage and loss of life on Crete and at Alexandria. It badly damaged the Lighthouse of Alexandria. Tectonic setting The Hellenic arc, the most likely location for this earthquake, is an arcuate tectonic feature related to the subduction of the African Plate beneath the Aegean Sea Plate. It is one of the most active seismic zones in western Eurasia and has a history of large earthquakes that also affect Egypt. Damage The earthquake and the tsunami are recorded as having a devastating impact on Heraklion, Crete. Detailed information is available from reports made by representatives from Heraklion (then Candia) to the controlling Venetian administration, written on the day of the earthquake and twenty days later. They describe the extent of damage to the main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epicenter
The epicenter, epicentre () or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates. Surface damage Before the instrumental period of earthquake observation, the epicenter was thought to be the location where the greatest damage occurred, but the subsurface fault rupture may be long and spread surface damage across the entire rupture zone. As an example, in the magnitude 7.9 Denali earthquake of 2002 in Alaska, the epicenter was at the western end of the rupture, but the greatest damage was about away at the eastern end. Focal depths of earthquakes occurring in continental crust mostly range from . Continental earthquakes below are rare whereas in subduction zone earthquakes can originate at depths deeper than . Epicentral distance During an earthquake, seismic waves propagate in all directions from the hypocenter. Seismic shadowing occurs on the opposite s ...

Venice
Venice ( ; it, Venezia ; vec, Venesia or ) is a city in northeastern Italy and the capital of the Veneto region. It is built on a group of 118 small islands that are separated by canals and linked by over 400 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po and the Piave rivers (more exactly between the Brenta and the Sile). In 2020, around 258,685 people resided in greater Venice or the '' Comune di Venezia'', of whom around 55,000 live in the historical island city of Venice (''centro storico'') and the rest on the mainland (''terraferma''). Together with the cities of Padua and Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million. The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC. The city was historica ...

Adriatic
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexis Perrey
Alexis Perrey (1807–1882) was a historical French seismologist and compiler of earthquake catalogs. He is considered a pioneer in this area, having published a paper on earthquakes in Algeria ) , image_map = Algeria (centered orthographic projection).svg , map_caption = , image_map2 = , capital = Algiers , coordinates = , largest_city = capital , relig ... as early as 1848, in the journal '' Mémoires de l'Académie des Sciences, Arts et Belles-Lettres de Dijon''. He continued to post annual observations on Algerian earthquakes until 1871. He suspected a correlation between the moon and seismic activity on earth, and developed his theory with the use of statistics. He found that earth tremors occurred most frequently during full and new moons, when the earth is between the sun and moon, when the moon is between the earth and sun, and when the moon is closest in its orbit to the earth. He als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seven Wonders Of The World
Various lists of the Wonders of the World have been compiled from antiquity to the present day, in order to catalogue the world's most spectacular natural features and human-built structures. The Seven Wonders of the Ancient World is the oldest known list of this type, documenting the most remarkable man-made creations of classical antiquity; it was based on guidebooks popular among Hellenic sightseers and as such only includes works located around the Mediterranean rim and in the ancient Near East. The number seven was chosen because the Greeks believed it represented perfection and plenty, and because it reflected the number of planets known in ancient times (five) plus the Sun and Moon. Seven Wonders of the Ancient World The Greek historian Herodotus (484 – c. 425 BC) and the scholar Callimachus of Cyrene (c. 305–240 BC), at the Museum of Alexandria, made early lists of seven wonders. These lists have not survived, however, except as references in other writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosque
A mosque (; from ar, مَسْجِد, masjid, ; literally "place of ritual prostration"), also called masjid, is a place of prayer for Muslims. Mosques are usually covered buildings, but can be any place where prayers ( sujud) are performed, including outdoor courtyards. The first mosques were simple places of prayer for Muslims, and may have been open spaces rather than buildings. In the first stage of Islamic architecture, 650-750 CE, early mosques comprised open and closed covered spaces enclosed by walls, often with minarets from which calls to prayer were issued. Mosque buildings typically contain an ornamental niche ('' mihrab'') set into the wall that indicates the direction of Mecca (''qiblah''), Wudu, ablution facilities. The pulpit (''minbar''), from which the Friday (jumu'ah) sermon (''khutba'') is delivered, was in earlier times characteristic of the central city mosque, but has since become common in smaller mosques. Mosques typically have Islam and gender se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minaret
A minaret (; ar, منارة, translit=manāra, or ar, مِئْذَنة, translit=miʾḏana, links=no; tr, minare; fa, گلدسته, translit=goldaste) is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer (''adhan''), but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires. Etymology Two Arabic words are used to denote the minaret tower: ''manāra'' and ''manār''. The English word "minaret" originates from the former, via the Turkish version (). The Arabic word ''manāra'' (plural: ''manārāt'') originally meant a "lamp stand", a cognate of Hebrew '' menorah''. It is assumed to be a derivation of an older reconstructed form, ''manwara''. The other word, ''manār'' (plural: ''manā'ir'' or ''manāyir''), means "a place of light". Both words derive from the Arabic root ''n-w-r'', which has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Pyramid Of Giza
The Great Pyramid of Giza is the biggest Egyptian pyramid and the tomb of Fourth Dynasty pharaoh Khufu. Built in the early 26th century BC during a period of around 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only one to remain largely intact. As part of the Giza pyramid complex, it borders present-day Giza in Greater Cairo, Egypt. Initially standing at , the Great Pyramid was the tallest man-made structure in the world for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the present . What is seen today is the underlying core structure. The base was measured to be about square, giving a volume of roughly , which includes an internal hillock. The dimensions of the pyramid were high, a base length of , with a seked of palms (a slope of 51°50'40"). The Great Pyramid was built by quarrying an estimated 2.3 million large blocks weighing 6 million ton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
